Hey Lifesrun! I have a cab almost exactly the same size as yours. :thumbsup:

The closer you can get the lights, the less the plants will stretch. But you have to be careful not to fry them. Get a fairly good sized fan blowing a gentle breeze between the lights and the fan and this will not only keep the temps down, but the breeze really helps to strengthen your stems.

BTW - I flower under 1,200 watts in that cab. You are going to have to re-think your lighting when it comes time to flower as you don't have anywhere near what you need for that.
